Next time on "90210", Naomi finds out she can now access the money in her trust fund, so she decides to throw a giant birthday party where The Honey Brothers (featuring Adrian Grenier) perform a few songs. Dixon, Navid and Liam decide to take Oscar (Blair Redford) out for a night on the town, but their party ends when Ivy finds a Facebook photo of Dixon doing a body shot off a girl.

Annie has an instant connection with Charlie (Evan Ross), a guy she meets at a coffee shop, but seems more interested in exploring her relationship opportunities with Liam. Jen (Sara Foster) is forced to go on bed rest until she delivers the baby and has no choice but to allow Ryan into her life. Silver confronts Teddy about his drinking problem.

"Gossip Girl" takes over the next hour. Living out a real-life fairytale in Paris, Blair is pursued by a handsome young man, Louis (Hugo Becker), whom she suspects is a member of Monaco's royal family. A very concerned Lily asks Serena to help her find Chuck, who hasn't been heard from or seen in months.

Meanwhile, Chuck Bass is as we've never seen him before, adjusting to a fresh start in Paris with a mysterious new woman, Eva (Clemence Poesy), at his side. Juliet (Katie Cassidy) offers to help Nate win Serena back, suggesting that reigniting Dan and Vanessa's romance may just be the trick to remove Dan from the Dan-Serena-Nate love triangle
